Howard Junior School has taken the unprecedented step of banning its parents from sports day

In a letter to parents, headteacher Gregory Hill said staff had been threatened in an "intimidating and aggressive manner" by an "extremely small minority of parents".

In a letter, titled "Heightened Security", he explained: "If parents cannot conduct themselves appropriately, then to ensure the safety of staff, pupils and indeed other parents, we have decided that this year's sports day will take place with pupils only and unfortunately, parents are now not invited.

"This decision has not been taken lightly and is a real shame for the children, but we need to guarantee the safety of our staff and pupils."

Mr Hill said that there had been an increased policy and security presence at the school, sparked by the aggressive behaviour.

He said: "This has resulted from the actions of an extremely small minority of parents who have taken it upon themselves to threaten staff in an intimidating and aggressive manner."

He said "totally unacceptable" abusive language had been used in front of children and carried on, writing: "The school will continue to ban parents who conduct themselves in an inappropriate manner.

"All incidents of intimidation, violence or threatened violence will be reported to police."

Police have confirmed officers were called to the mixed state school in King's Lynn, Norfolk, on two occasions since June.

A furious mother said she was disappointed at the decision and claimed: "There are a lot of angry parents about this."

She said several parents were now considering taking their children out of the school as their views "aren't listened to."

Furious parents said having a sports day would be pointless, with one writing: "No point having a sports day if parents aren't there."

Another added: "Completely understand having the parents who have a history of aggression banned but not all of the innocent parties too!

"The head does need to protect the teachers, no-one should feel threatened while at work, but I don't think punishing the entire school is the way to go, this will just create more tension between staff and parents that were fine before."

Another claimed her children didn't want to do sports day after the announcement.

Police in Kings Lynn confirmed that officers were called to two incidents at the school - a "low level" one in June which has since been resolved and another this week which was being investigated.

The school has about 150 seven to 11-year-olds on its roll.

The Sun Online has contacted the school for comment.
